Resolving cavitation in silica-filled styrene-butadiene rubber composites upon cyclic tensile testing

Crack propagation in filled elastomers: 3D study of mechanisms involving the filler agglomerates

“…For this reason, instead of relaxing concentration by cavitation at their poles, one observes, at sufficiently large deformation, that these CBaggl do it by their internal fracture [26] (Figure 9). Such agglomerate fracture mechanisms were previously reported in the literature for materials containing silica agglomerates that has undergone fatigue [53] or quasi-static tests [8]. This is also consistent with the higher Mullins effect of the F1 material (shown by its higher ∆𝑈 , Figure 5) since it contains more agglomerates.…”

“…Since 1950s, many researchers extensively studied these properties in rubber materials. Rupture is the consequence of the initiation and propagation of a crack or multiple cracks through the entire section of the material, for instance, during fatigue [5][6][7] monotonic cycle [8] or quasistatic [9,10] solicitation. In some cases, crack propagation mostly dictates the durability of the material.…”

A novel strategy to functionalize styrene butadiene rubber toward enhanced interfacial interaction with silica

“…Saikat Das et al grafted propyltriethoxysilane onto SBR molecular chain by melting method 34 . However, few reports study on functionalization of SBR latex, while most of the existing studies are focused on natural rubber latex or SBR in solution 35–39 …”

“…34 However, few reports study on functionalization of SBR latex, while most of the existing studies are focused on natural rubber latex or SBR in solution. [35][36][37][38][39] Therefore, we attempt to enhance the dispersion uniformity of silica nanofillers in SBR matrix. To achieve this, we first established a redox initiator system in SBR latex, and then grafted hydroxyethyl acrylate (HEA) groups onto SBR molecular chains, thereby obtaining the SBR-g-HEA.…”

Study on volume change and scanning electron microscope observation of carbon black‐filled natural rubber upon stretching

“…Theoretical calculations using specific models to estimate volume changes have also drawn some researchers' interest. [12,[15][16][17][18][19][20] In recent years, there have been some new methods of measuring volume change, for example by video camera [21,22] or digital image correlation, [23] also microcomputed X-ray tomography, [24,25] which can obtain experimental data conveniently. Through a long period of exploration, it has been gradually recognized that the volume change of vulcanizates during extension is closely related to straininduced crystallization, formation and breakdown of filler agglomerates.…”
